The invention designs a helicopter hanging variable body stability augmentation device, and belongs to the field of helicopters. The device comprises a thrust set composed of four ducted fan air injection devices, a ducted fan thrust direction changing mechanism and a box body connecting device. When the hanging object swings and rotates, the thrust set composed of the four ducted fan air injection devices generates force and torque for restraining the hanging object from swinging and rotating, and therefore the effect of reducing the swinging and rotating amplitude is achieved. Meanwhile, self-adaptive layout change can be carried out according to the environment state, and the stability augmentation requirement can be met in various scenes. Compared with an existing stability augmentation device, the structure is simpler, and adaptability is higher.

    本发明设计了一种直升机吊挂可变体增稳装置,属于直升机领域。该装置包含由四个涵道风扇喷气装置组成的推力组,涵道风扇推力变向机构,箱体连接装置。当吊挂物发生摆动与旋转时,由四个涵道风扇喷气装置组成的推力组产生抑制其摆动与旋转的力与力矩,从而达到减小摆动与旋转幅度的效果。同时可以根据环境状态进行自适应布局改变,能够在多种场景下满足增稳需求。相比之前的增稳装置,结构更简单,适应性更强。
